  • 1. PCTE Introduction to Microprocessor 1 PUNJAB COLLEGE OF TECHNICAL EDUCATION COURSE – PLAN (Jul 10 – Dec 10) SUBJECT: Introduction to Microprocessor CODE: BC – 305 (N2) CLASS: BCA – 3rd Sem SECTION: C, D TEACHER: Gursharan Singh (GS) Course Description: This course is an introduction to microprocessor. In this class, we will focus on microprocessor design, including CPU and memory, the interface between hardware and software, and an introduction to microprocessors programming techniques. More specifically, we will cover the following topics:  Introduction to Microprocessor  Architecture and Operations of Intel 8085  Architecture and Operations of Intel 8086  Various types of Instructions  Clock Generator 8284  Interrupt Controller 8257  DMA Controller 8237  Arithmetic Coprocessor 8087 Prerequisites: Students should have basic knowledge of following topics for the better understanding of concepts of microprocessor:  Binary and Hexadecimal Number Systems  Logic Gates, Boolean Algebra  Sequential Digital Circuits and Design  Combinational Digital Circuits and Design
  • 2. PCTE Introduction to Microprocessor 2 Course Goals: The goal of this course is for you to learn microprocessors systems, their organization and architecture, develop an understanding of programming techniques, program debug and programming languages. The course includes topics on CPU internal architecture, instruction set, CPU timing, and machine and instruction cycles. Decoding memory addresses or I/O port addresses. The objective of this course is to:  Students should be able to describe the architecture and organization of a microprocessor.  Students should be able to write structured, well-commented, understandable programs in assembly language.  Students should possess the skills to test and debug microprocessor programs in the laboratory.  Students should understand techniques for interfacing I/O devices to the microprocessor, including several specific standard I/O devices.  Students should understand the hardware/software tradeoffs involved in the design of microprocessor-based systems.  Understand processor design concepts in modern computer architecture.  Enable you to design and build a mini computer. Scope and Opportunities: This course offers an opportunity to be at the forefront of the emergent practice of modern microprocessor architecture. The graduates of this course can be absorbed in the mainstream of Microcontroller Programming or many related fields like Architectural Visualization, Building Management Systems, Software Development, etc. Grading: MSE: 15 marks st 1 One Hourly Test: 5 marks 2nd One Hourly Test: 5 marks Presentation: 5 marks Class Tests: 5 marks
  • 3. PCTE Introduction to Microprocessor 3 Assignments: 5 marks Total: 40 marks Rules for Assignments: Purpose: The assignments will primarily be practice problems for the exams. Thus, you should not collaborate on it with others by splitting the work and sharing answers. You will gain the most benefit from doing it by yourself. You can, of course, ask me for help. If someone in the class asks you for help on assignments, handle the situation as if you are a course instructor. Don’t just give them an answer, but make sure they know how to find the answer on their own. If I feel that people have submitted answers that are merely copies of each other, I will grade the one solution and divide the credit for it equally among the copies. Due Date: As indicated in the course break-up below. Late Policy: You must do your work on time because we'll be correcting/discussing it in class. No assignment will be accepted after the due date. If you know that you have a specific time conflict, make arrangements with me in advance for a separate assignment for late submission. Format: All assignments should be done according to the following format:  Assignment must have a cover page including title of assignment, subject, date of submission, students name, class, roll no. and submitted to.  For a sample of cover page, visit my website http://www.eazynotes.com.  Use loose sheets with one side plain and other side lined.  Write questions/headings with black pen and other text with blue pen.  Draw diagrams (if necessary), neat and clean with pencil on plain side of paper.  Pages should be numbered.  Mention Contents at the beginning and References at the end of each assignment.
  • 4. PCTE Introduction to Microprocessor 4 Tests: Tests can be oral/written/open book. Open book test is so that you can look up formulas or data from the text or lecture notes. You need to be sufficiently familiar with the material in the book to know where to look up the information that you need. The purpose of the exams is for you to demonstrate that you have attained an operational level of understanding of the material. The tests will be conducted on the dates mentioned in the course break-up. No extra test will be conducted for the absentees. If you have any time conflict for the test, contact me in advance so that we can make sufficient arrangements. Keep in mind that there will be no improvement test at the end of the semester. Therefore, it’s your responsibility to give test on time. Presentation: One presentation will be held for microprocessor. You will be informed well in advance. The rules for presentation are as follows:  Group will be of 3-4 students.  Students can make groups of their choice.  Students should be in strict formals for the presentation.  Three attendances will be taken during presentation. One at sharp 9:00 am, second after lunch break, and third at the end of the presentation.  Present will be counted only for those students who’ll be present in all the three attendances.  Marks will be given only to the present students.  If the student is absent, I will deduct (– 10) marks for it.  Marks will be deducted for each misbehavior/indiscipline during the presentation.  Topics will be given at first-cum-first-get basis. No topic will be repeated.  Marks for the presentation are distributed as follows: Dress: 10 marks Report: 10 marks Content: 10 marks Slides: 5 marks Confidence: 5 marks
  • 5. PCTE Introduction to Microprocessor 5 Query Handling: 10 marks Total: 50 marks Absent: – 10 marks Indiscipline: – 1 marks (for each misbehavior) Class Participation: A large component of your learning takes place in class. The actual concepts of microprocessor are fairly simple, although their implementation is often complicated by real- world constraints. Thus, I tend to give lectures to explain these concepts, and pose questions for discussion that are meant to draw out these implications. I will guide discussion, and add information here and there as necessary to carry the discussion forward or to lead it into a digression that adds depth in a different direction. I will frequently have in-class exercises that you will do as individual/groups. Thus, it is very important that you attend class regularly. I will keep attendance throughout the semester. Please let me know in advance of any scheduled absences. Classroom Policies: Following are the classroom policies and they are meant to be strictly followed:  Be punctual for the class; try to minimize your disturbance if you are late. I may reject students who come after 15 minutes from the scheduled time.  Student coming late will be considered as late arrival and I will record late arrivals on the day’s attendance.  Three late arrivals equals to one absent.  Mobile phones are not allowed in the classroom. If any student found using the mobile phone, he/she has to pay Rs. 200 as fine in the account office.  During lecture delivery, if you have any kind of query, just raise your hand. Queries are important for the understanding of the concepts. So, do ask queries but make sure they are relevant to the subject.  Be disciplined in the classroom and don’t make any noise while we are studying.
